Constraining the synchrotron peak and estimating the VHE brightness of a sample of extreme high synchrotron peak blazars
Federica Sibani, Stefano Marchesi, Ettore Bronzini +5
We present the results of a multi-wavelength study of a population of X-ray bright (), non--ray detected high and extreme high synchrotron peak…
CTAO LST-1 observations of magnetar SGR 1935+2154: Deep limits on sub-second bursts and persistent tera-electronvolt emission
K. Abe, S. Abe, A. Abhishek +333
The Galactic magnetar SGR 1935+2154 has exhibited prolific high-energy (HE) bursting activity in recent years. Investigating its potential tera-electronvolt counterpart could provi…
The link between galaxy merger, radio jet expansion and molecular outflow in the ULIRG IRAS 00183-7111
Ilaria Ruffa, Marilena Spavone, Enrichetta Iodice +8
The ultraluminous infrared galaxy (ULIRG) IRAS 00183-7111 () is one of the three ULIRGs that are currently known to host an active galactic nucleus (AGN) with small-scale…
XXL-HSC: Host properties of X-ray detected AGNs in XXL clusters
E. Drigga, E. Koulouridis, E. Pouliasis +10
There is compelling evidence that AGNs are strongly influenced by their environment. Therefore, studying the AGN population of clusters is essential, as both large-scale structures…
A New Hope for Obscured AGN: The PRIMA-NewAthena Alliance
Luigi Barchiesi, F. J. Carrera, C. Vignali +8
Understanding the AGN-galaxy co-evolution, feedback processes, and the evolution of Black Hole Accretion rate Density (BHAD) requires accurately estimating the contribution of obsc…
Going deeper into the dark with COSMOS-Web: JWST unveils the total contribution of Radio-Selected NIRfaint galaxies to the cosmic Star Formation Rate Density
Fabrizio Gentile, Margherita Talia, Andrea Enia +34
We present the first follow-up with JWST of radio-selected NIRfaint galaxies as part of the COSMOS-Web survey. By selecting galaxies detected at radio frequencies ($S_{\rm 3 GHz}>1…
HYPERION: broad-band X-ray-to-near-infrared emission of Quasars in the first billion years of the Universe
I. Saccheo, A. Bongiorno, E. Piconcelli +41
We aim at characterizing the X-ray-to-optical/near-infrared broad-band emission of luminous QSOs in the first Gyr of cosmic evolution to understand whether they exhibit differences…
HYPERION. Shedding light on the first luminous quasars: A correlation between UV disc winds and X-ray continuum
A. Tortosa, L. Zappacosta, E. Piconcelli +41
One of the main open questions in the field of luminous () quasars (QSOs) at is the rapid formation (Gyr) of their superm…
A Multi-Wavelength Characterization of the Obscuring Medium at the Center of NGC 6300
D. Sengupta, N. Torres-Albà, A. Pizzetti +9
Most of the super-massive black holes in the Universe accrete material in an obscured phase. While it is commonly accepted that the "dusty torus" is responsible for the nuclear obs…
Towards a response function for the COSI anticoincidence system: preliminary results from Geant4 simulations
Alex Ciabattoni, Valentina Fioretti, John Tomsick +9
The Compton Spectrometer and Imager (COSI) is an upcoming NASA Small Explorer satellite mission scheduled for launch in 2027 and designed to conduct an all-sky survey in the energy…
Euclid preparation. XLIX. Selecting active galactic nuclei using observed colours
Euclid Collaboration, L. Bisigello, M. Massimo +244
Euclid will cover over 14000 with two optical and near-infrared spectro-photometric instruments, and is expected to detect around ten million active galactic nuclei (AGN)…
Investigating the nuclear properties of highly accreting active galactic nuclei with XMM-Newton
M. Laurenti, F. Tombesi, F. Vagnetti +7
Our understanding of highly accreting AGNs is hampered by the lack of a complete systematic investigation in terms of their main spectral and variability properties, and by the rel…
XMM-Newton Ultra Narrow Deep Field survey II: X-ray spectral analysis of the brightest AGN population
M. Elías-Chávez, A. L. Longinotti, Y. Krongold +6
In this work, we present the results of a detailed X-ray spectral analysis of the brightest AGNs detected in the XMM-Newton 1.75 Ms Ultra Narrow Deep Field. We analyzed 23 AGNs tha…
AGN X-ray luminosity function and absorption function in the Early Universe ()
E. Pouliasis, A. Ruiz, I. Georgantopoulos +15
The XLF of AGN offers a robust tool to study the evolution and the growth of SMBHs over cosmic time. Owing to the limited area probed by X-ray surveys, optical surveys are routinel…
The XXL survey LII : The evolution of radio AGN luminosity function determined via parametric methods from GMRT, ATCA, VLA and Cambridge interferometer observations
B. Šlaus, V. Smolcic, Ž. Ivezic +6
We model the evolution of active galactic nuclei by constructing their radio luminosity functions. We use a set of surveys of varying area and depth, namely the deep COSMOS survey…
Probing supermassive black hole growth and its dependence on stellar mass and star-formation rate in low-redshift galaxies
